Ok, back again! Do you think she could cope with a little more A time at the beginning of the day? She's getting a 45min nap off a 3h15min A time, or thereabouts? Have you tried 3.5h? You might find it easier to extend the nap if she's more tired for it in the first place. Her nights actually sound quite good really, I'm just thinking if we can push her naps a bit later (and hopefully get them longer too) then she should be able to get to BT without the OT which could be leading to the NWs in the early evening. Then if she has her first night feed on the later side, she may be able to get through until morning without another feed?
As for how to go about extending naps - how does she respond best at the start of a nap? Does she always settle independently straight away? If you sometimes help her, what do you do? You can do the same when she wakes from a nap - but first give her a chance to see if she'll resettle herself, rather than getting her up straight away. Don't worry if she's making little fussing noises, only go in if she's crying "I need you". If she usually settles independently at the start of a nap, but cries "I need you" after a short nap, then go in to her and see if you can reassure her, tell her it's sleepy time (or whatever phrase you use to tell her it's nap time) and see if she calms down. Even if she doesn't after a while you can still leave the room for a couple of seconds and then go back in and comfort her again. She may not understand at first, if she's used to you going in as soon as she wakes, but eventually she'll work out that you want her to go back to sleep, and if she's tired enough then she might manage it. Even if not, if you stay consistent she may get it the next time, or after a few attempts. Definitely worth trying. Have a read here:
Getting back on track using Walk In/Walk Out (WI/WO)Alternatively, there's the wake to sleep method which I linked to above.
